What Is Digital Photogrammetry?
In general, digital photogrammetry is the art of using computers to obtain the measurements of objects in a photograph. It typically involves analyzing one or more existing photographs or videos with photogrammetric software to determine spatial relationships. Although commonly used to create topographical maps, it may also be useful in a variety of industries such as architecture, manufacturing, police investigation, and even plastic surgery.

Although commonly used to create topographical maps, it may also be useful in a variety of industries such as architecture, manufacturing, police investigation, and even plastic surgery. There are several important variables involved in digital photogrammetry. First, it may be useful for a photogrammetrist to know information about the camera, such as what type of camera took the photograph, the focal length of the lens, or the distance of the camera to the object of interest. A special type of camera, called a metric camera, is often used to take these photographs because it is calibrated to take precision photographs with little lens distortion.
